Keypad Type STS Standard Pre-payment GPRS/RF/PLC Module Slot Intelligent Single Phase Electric Power Meter
STE18-G is STS standard keypad single phase electricity meter with a plug-in module for STS compliant data collection and network communications. This modular design enables utility to select from PLC/RF/GPRS according to local conditions. Upgrade and maintenance will also become cost-effective by replacing the modules only instead of the entire meter.
Meter can be top up with Stronpay vending software directly, or integrated our vending with local mobile payment via API. People can recharge with mobile phone without leaving their house. It allso can communicate with AMI system with GPRS module or LORA-RF/PLC module and DCU directly. Utilities can read, control and recharge the meter remotely.
